The STM8L101G3U6TR is an ultra-low-power 8-bit MCU from STMicroelectronics, running at 16MHz with 8KB flash and 1.5KB RAM. Its 1.65V to 3.6V supply range supports single-cell battery operation. Housed in a 28-UFQFN package, it integrates infrared, POR, PWM, and WDT for compact, energy-efficient designs.

  • Ultra-low voltage: Operates down to 1.65V for direct battery use.
  • Integrated IR: Built-in infrared support reduces external components.
  • Compact size: 28-UFQFN ideal for miniaturized wearables.
  • Low power: STM8 core optimized for energy-sensitive applications.

Battery-Powered Remote Controls

The 1.65V minimum voltage and infrared support make it perfect for low-power IR remotes.

Wearable Health Trackers

Ultra-low voltage operation and 16MHz speed enable compact fitness bands with basic sensor fusion.

IoT End Nodes

8KB flash fits lightweight protocols for smart home sensors operating at 3V coin cells.

Portable Consumer Electronics

The 28-UFQFN package and low power suit small handheld gaming or calculator devices.

Simple Motor Drivers

PWM output allows speed control in toys or small fans with minimal external components.

Security Keypads

WDT and POR ensure reliable operation in access control panels with limited power budget.
